大兴安岭南东段龙头山银铅锌多金属矿床成矿地质特征与远景评价

文章阐述了龙头山银铅锌多金属矿床的地质特征,初步确定了矿床的成矿期与成矿阶段、蚀变作用与蚀变分带,以及控矿构造系统与空间变化等;通过合理的探矿工程并借助于先进的地球物理探测手段,基本探明了Ⅰ、Ⅱ号矿带内矿体的空间产出形态、规模和产状,大致查明了矿石的类型、结构构造以及矿化特征,并合理地圈定了矿体;通过综合取样分析,估算并预测了远景资源储量.

THE GEOLOGICAL ORE-FORMING FEATURE AND RESOURCE ESTIMATION OF THE SILVER POLYMETALIC DEPOSIT IN SOUTHEAST PART OF DA HINGGAN LING AREA

This paper studied the geological features of Longtoushan deposit for the first time, and determined the principal metallogenic events and ore-forming series, alteration zoning, the ore-control structures system and its space change. With the elaborate technology of geophysical exploration and prospect engineering we examined the mineralizing belts and promising section and confirmed ore body distribution, size and configuration in space. We recognized the ore types, their structures and texture, made sure the ore bodies boundary, and estimated perspective resources depending on the integrated chemical analysis.
